If one would visit DotA-Allstars.com now, one can no longer see the usual homepage. In its place is a letter from the webmaster, Pendragon talking about the closure of DotA-Allstars. In the letter, he expresses his growing responsibilities with LoL and his declining passion in DotA that led to his decision.
He also expresses that while the site will be closed down, all its content so far will be kept intact and moved to a permanent server for archiving. Finally he reveals a little about what happened between him and IceFrog that caused the split.
